The Study for the Breakdown Characteristics of Interface between LSR-XLPE, EPDM-XLPE by the Interfacial Treatment Condition

LSR-XLPE, EPDM-XLPE 이종계면에서의 계면처리에 따른 절연파괴특성

In this paper, we studied the properties of a cable insulate capacity between surfaces with the variation of the interfacial breakdown. As a function of silicon oil, the variation of pressure and interfacial roughness were investigated. The insulate trouble of a power cable is out of the interfacial parts, which breakdown the insulate breakdown capacity in a power cable. In this study, the analysis of electric field and the phenomenon of interfacial breakdown were improved by increased interfacial pressure, decreased surface roughness, and oil. And It was shown that interfacial breakdown LSR-XLPE insulators is higher that of EPDM-XLPE.
